Not really inside information......
Not to get into semantics, it's second/third etc..hand information that is not published. Afaik, there is only one published rating, that which the OP posted. So if not inside info, then non published information which is what my post went on to explain.
Also, not all MC oil filters have thread end bypass, though it appears most do. And, not all the applications are readily available from places like Wally or Advance. Those that are, like the FL820-S and some others are value priced. Others have to be obtained from places like the dealer at their price.
Again, MC's are a well made filter, that are made/designed to meet FoMoCo specs.
